Your pregnancy: weeks 5 to 8

Your baby

Over these next few weeks, your baby will grow to be about 1 inch long and develop arms, legs, muscles, and skin. If you could see your little one, you’d notice that the head is much bigger than the rest of his or her body, because your baby’s brain is growing faster than any other organ.

Right now, there’s a little lump forming in the center of the embryo. It’s my baby’s heart, and I’m in love.

Your body

You may start to notice early signs of pregnancy: Feeling tired, tender breasts, and nausea are all common. So are craving new foods and suddenly being disgusted by foods you used to love. Your sense of smell might be in overdrive — some women can’t even stand the smell of their favorite flowers during pregnancy. All of this is normal, and temporary.

Feeling moody? That’s your hormones working overtime. And with so many changes happening in your life, it’s natural to feel many different emotions. Talking things over with a trusted friend can help you handle the ups and downs.

Your to-do list

Schedule your first prenatal care visit. We typically recommend having your first prenatal appointment between weeks 7 and 12.

If you take medication, ask your doctor if it’s okay to keep taking it while you’re pregnant.
